In recent years the use of electronic control systems has become increasingly popular in automotive applications, resulting in significant improvement in vehicle stability and dynamic performance. Especially, ESC (Electronic Stability Control) as an active safety technology assists the driver to keep the vehicle on the intended track and thereby actively prevents accidents. But most electronic chassis control systems so far have been designed for optimization of its own performance. This, sometimes, has resulted in performance degradation when two or more control modules were operating together. Therefore, many studies are shown that is being given to judicious integration of individual chassis control systems in an effort to push the overall vehicle performance further to its limit. In this paper, ESC contributions to active safety and CDC (Continuous Damping Control) to semi active suspension have been present with a reliable simulation environment. Then, algorithms for integration of suspension and brake control systems have been developed. An integrated approach for braking and suspension control for maximum lateral stability that is an optimal collaboration between the brake & suspension with respect to maximum stability in highly dynamic maneuvers, various integration rules have been designed, tested, and compared with one another, and the results will be investigated in this paper.
